I have a Kenwood indash dvd player with front AV jack. Is there a cord that I can buy that will let me do this? I want to be able to play Pandora, etc.
Well you got the HDMI out via your adapter.... to get to composite video you need a converter. I do not believe you can do this with a simple cable. A converter can do it, would probably run you around $50, be housed in a box, and require power. Something like this...
That is the case unless there is some other method to get the infuse to feed out composite directly. I haven't seen anything to suggest this though.
If its just audio, then yes, there are plenty of cables that will go from the TRS connector (aka mini-plug, aka 3.5" headphone jack) to RCA stereo audio. Or to another 3.5"...
These are quite cheap online, though I imagine you could get one at any local electronics store like Radio Shack or Best Buy if you don't mind paying a bit more.
